What are the REACH regulatory requirements for PV energy storage components? REACH is the EU regulation concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals.
For finished PV energy storage products, the most critical aspect involves obligations regarding “articles”: if SVHC content exceeds 0.1%, downstream users and consumers must be notified; if the volume exceeds 1 tonne per year, notification to ECHA is required within six months;
and if limits are exceeded, SCIP notification is also mandatory. Energy storage batteries are additionally subject to the restrictions in REACH Annex XVII (limits on lead, cadmium, and mercury).
I. What is REACH? Its Four Pillars
- REACH = EU Regulation on the Registration, Evaluation, Authorisation and Restriction of Chemicals (EC No 1907/2006).
It entered into force on June 1, 2007, to protect human health and the environment, and is enforced by ECHA (European Chemicals Agency) (Source: EU/Intertek). - Registration: Substances (on their own or in mixtures) produced or imported at ≥1 tonne per year must be registered with ECHA;
products cannot be placed on the market without registration (“no data, no market”) (Source: EU/Intertek). - Evaluation: ECHA reviews registration dossiers and substance risks.
Authorisation: SVHCs included in the Authorisation List (Annex XIV) are banned after the “sunset date” unless specific authorization is granted (Source: EU/Intertek). - Restriction: Covers restricted chemicals listed in Annex XVII;
as of April 2026, there are 83 entries (e.g., azo dyes, phthalates, cadmium content, nickel release) (Source: Intertek). - Roles Covered: Manufacturers, importers, distributors, and downstream users all have obligations; non-EU enterprises may appoint an “Only Representative” to fulfill these obligations on their behalf (Source: EU).

Obligations Related to Articles (Crucial for PV Energy Storage)
- SVHC > 0.1% (by weight): Suppliers of articles must provide safe-use information to downstream users and—upon consumer request—provide the substance name and content free of charge within 45 days (Article 33) (Source: Conphora/WTO).
- SVHC > 0.1% and total annual volume > 1 tonne: Manufacturers/importers must notify ECHA within 6 months (Article 7) (Source: WTO/Intertek).
- SCIP Database: For articles containing > 0.1% SVHC, identification information regarding the article and the SVHC must be submitted to the ECHA SCIP database (Waste Framework Directive; effective Jan 5, 2021) (Source: TÜV SÜD/WTO).
- Determination for Complex Articles: Calculated based on 0.1% per article (Case C-106/14);
complete units/assemblies are assessed layer by layer (Source: Conphora). - Imported Article Restrictions: Each import batch is checked against Annex XVII entries (concentration limits/test methods/effective dates);
items such as cadmium and phthalates are verified individually (Source: Conphora).

REACH Applicability and Restrictions for PV Energy Storage Components
- PV Modules: Explicitly excluded from RoHS (Article 2(4)(h)); compliance obligations regarding lead stem from REACH Article 33 SVHC notification and WEEE recycling requirements;
perovskites/lead iodides must be checked against the ECHA Candidate List (Source: Asaptic). - Energy Storage Batteries: Subject to REACH Annex XVII restrictions—lead ≤ 0.01% (100 ppm), cadmium ≤ 0.002% (20 ppm), and mercury ≤ 0.0005% (5 ppm); mandatory as of Feb 18, 2024 (Source: TÜV SÜD).
- Overlapping battery regulations: Article 6 of EU Battery Regulation 2023/1542 requires batteries to simultaneously meet the restrictions of REACH Annex XVII, the ELV Directive, and Annex I of the Battery Regulation (Source: TÜV SÜD).
- Common battery SVHCs: Solvents such as N-Methyl-2-pyrrolidone (NMP) are commonly found in battery cell/electrode materials;
information communication and SCIP notification are required (Source: TÜV SÜD). - EN 50581:2026 (Mandatory from Nov 1, 2026): PV inverters, ESS control units, and hybrid energy storage systems must submit a Digital Chemical Declaration (DCD) covering RoHS, REACH, POPs, and PFAS, subject to verification by an EU-authorized body (Source: GISN).
IV.
SVHC List and Updates
- SVHC Candidate List: 253 substances across 36 batches (n-hexane and bisphenol AF and its salts added on Feb 4, 2026); updated twice annually in June and December (Source: WTO).
- Examples of new additions: n-hexane (neurotoxicity/equivalent level of concern [ELOC]), bisphenol AF (reproductive toxicity);
proposal for bisphenol F was withdrawn (Source: WTO). - Products containing SVHCs are ineligible for the EU Ecolabel (Source: WTO).
- Substances on the Candidate List may move to the Authorization List in the future, requiring an authorization application for continued use (Source: Intertek/WTO).
- High-risk list coverage: Lead, cadmium, phthalates, and certain flame retardants are commonly found in electronic components and battery materials, with strong relevance to PV energy storage (Source: NovaEuris).
V.
Testing and Compliance Process
- SVHC identification: Request complete material declarations from suppliers (for battery cells, BMS, housings, cables) to confirm whether SVHC content exceeds 0.1% (w/w) (Source: NovaEuris).
- Due diligence testing: REACH does not mandate specific tests; targeted analysis is conducted by accredited laboratories (SGS/TUV/BV)—ICP-OES for metals and GC-MS for organic compounds—costing $500–$2,000 per product variant (Source: NovaEuris).
- Notification: EU importers or manufacturers must register on the ECHA portal to handle SVHC notifications;
reporting is mandatory if volume exceeds 1 tonne/year and concentration exceeds 0.1% (Source: NovaEuris). - Technical documentation: Retain the Bill of Materials (BOM), test reports, and supplier declarations for at least 10 years for potential market surveillance inspections (Source: NovaEuris/Conphora).
- Document maintenance: The ECHA Candidate List is updated semi-annually;
re-testing and updates to the Safety Data Sheet (SDS) and declarations are required if suppliers change materials or the list is updated (Source: NovaEuris).
VI. Responsible Parties and Latest Trends
- Responsible parties: REACH obligations fall on EU importers/manufacturers;
non-EU manufacturers may appoint an Only Representative (OR). Importers must verify manufacturer compliance and retain documentation for 10 years (Source: EU/Intertek). - April 27, 2026: EU abandons comprehensive REACH revision;
proposals such as 10-year registration validity and mandatory polymer registration are shelved, providing short-term planning stability for businesses (Source: WTO). - However, enforcement is intensifying: Border interceptions of non-compliant products and enhanced internal market surveillance;
amendments to Annexes can still raise compliance thresholds (Source: WTO). - PFAS restriction proposal is the next milestone, expected by late 2026;
supply chains involving fluorinated chemicals (PTFE/PVDF) require proactive screening (Source: WTO). - For PV and energy storage: The Digital Chemical Declaration (DCD, effective Nov 1, 2026), Battery Regulation requirements (carbon footprint/recycling), and EN 50581 are transforming chemical compliance from mere documentation into a hard requirement for market access (Source: GISN/TUV SUD).
VII. Procurement Recommendations
- Require SVHC declarations and test reports: Mandate that suppliers provide REACH/SVHC compliance documentation (material declarations, third-party reports, and Declarations of Conformity) and verify ingredients against the ECHA Candidate List (Source: NovaEuris).
- Conduct tiered checks based on PV and energy storage categories: For modules, check for Article 33 SVHC notifications and WEEE recycling compliance;
for energy storage batteries, check against REACH Annex XVII (limits on lead, cadmium, and mercury) and battery regulations; for inverters, check against EN 50581 DCD (Source: Asaptic/TÜV SÜD/GISN). - Incorporate REACH requirements into procurement contracts: Require delivery with SVHC declarations and test reports; make suppliers responsible for re-testing when the list is updated;
and hold suppliers liable for recalls and fines if products containing SVHCs fail to meet standards (Source: NovaEuris). - Establish compliance checkpoints: Check for SVHCs at three stages—design review, pre-production sampling, and pre-shipment;
update the list semi-annually and require suppliers to synchronize their data accordingly (Source: NovaEuris). - Prioritize mature supply chains: Select manufacturers that have dedicated REACH teams, experience exporting to the EU, and the capability to update documentation in line with list changes;
note that EU importers bear the responsibility for notification (Source: NovaEuris/EU).
Trends and Summary
- Chemical compliance is becoming a mandatory digital market access requirement: The EN 50581:2026 DCD (effective Nov 1, 2026) links RoHS, REACH, POPs, and PFAS declarations to market entry (Source: GISN).
- Continuous expansion of the SVHC list: The list is updated semi-annually (currently 253 substances across 36 batches);
products containing SVHCs are ineligible for eco-labels, driving the adoption of substitutes (Source: WTO). - Divergence between enforcement and regulatory revision: While formal revision of the REACH text is stalled, border enforcement is intensifying, and Annex requirements can be tightened quietly; do not let your guard down (Source: WTO).
- Overlapping Battery Regulation and REACH requirements: Limits on lead, cadmium, and mercury, plus carbon footprint, recycled content, and battery passport mandates, create multi-dimensional compliance constraints for energy storage chemistries (Source: TÜV SÜD).
- For purchasers, the answer regarding REACH requirements for PV and energy storage components is as follows: REACH is the EU regulation concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals.
For finished PV and energy storage products, the critical aspect is the obligation regarding “articles”: if SVHC content exceeds 0.1%, downstream users and consumers must be notified (Article 33); if volume exceeds 1 tonne/year, notification to ECHA is required within six months; and exceeding limits triggers SCIP notification. Specifics include: modules are exempt from RoHS (with lead covered by REACH and WEEE); energy storage batteries are subject to Annex XVII limits (Pb 100ppm/Cd 20ppm/Hg 5ppm) and the Battery Regulation; inverters are subject to EN 50581/DCD; the SVHC list (currently 253 substances) is updated semi-annually; documentation must be retained for 10 years;
and EU importers bear liability—requiring full SVHC declarations and test reports, verification across the supply chain, and the treatment of REACH compliance as a mandatory criterion for procurement acceptance.
